EMERGENCY-COUPLING..

SPECIFICATION forming part of Letters Patent No. 770,584, .datedSeptember 20, 1904.

Application filed J une 14, 1904.

To all wwnt t WMI/U concern:

Be it known that I, GEORGE J. HUBBARD, a citizen of the United States,and a resident of Port Jervis, in the county oi' Orange and State of NewYork, have invented a new and Improved Emergency-Ooupling,of which thefollowing is a full, clear, and eXact description.

The invention relates to railroad car-coup- 1ers; and its object is toprovide a new and improved emergency-coupling arranged to permit ofconveniently .tying or coupli-ng the draw-heads of adjacent carstogether in case the coupling mechanism ofthe said draw-heads is brokenor out of order.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a perspective View of the improvement as applied. Fig. 2 isan enlarged perspective view of the improvement, illustrating the stepfor closing the chain-loop by the detachable loop-closinglink. Fig. 3is'an enlarged cross-section of the chain, showing two links of thechain engaged with the detachable loop-closing link. Fig. l is aperspective view of the improvement,showing the chain-loop closed by adetachable loop-closing link of modiiied form; and Fig. 5 is a sideelevation of a loop-inclosing link of modified form.

The chain A of a suitable length is provided at-one end with a ring B toallow of passing the free end of the chain through the ring for forminga loop, adapted to engage the shank of a draw-head C for the loop toabut against the head o1u the draw-head, as plainly indicated inFig'. 1. The free end of the chain A, after engaging the draw-head O ofone Car, is passed around the shank or' the other draw-head,O, on theother car to form a loop around the same, as plainly indicated in Fig.l, and this loop is now closed by a separate or detachable loopclosinglink D engaging the chain-links A Serial No. 212,508. y(No model.)

and A2 of the chain A at the closing-point of the loop for the draw-headC.

and 3.) The separatelink Dis elongated, and one of its parallel membersis cut or split at the middle to practically form two hooks D and D2,having a common entrance D2, (see Fig. 3,) the hooks being adapted to behooked onto the chain-links A A2, so that the following chain-links onthe links A A2 stand at right angles to the detachable link D, and henceabut against the hooks D D2 to prevent drawing the chain through' thedetachable link D, which latter thus holds the loop around the draw-headO completely and perfectly closed, no matter in which direction thestrain is exerted on the chain A.

By the arrangement described the drawheads O and C of adjacent cars arecoupled or tied together by the chain A and the separatelink D to holdthe cars coupled together in case the coupling mechanism of thedrawheads C and C is broken or out of order.

ln the modiiied form (shown in Fig. 4) the separate link E is completelyclosed and has its middle portion E enlarged to permit of passing thefree end of the chain A through the enlarged portion E', the sides ofthe link, however, being formed into retaining members or hooks E2 E3for holding the links A A2 in position, the same as 'above described inreference to Figs. l, 2, and 3.

(SeeFigs. 1, 2,

In using the chain A with the link E the chain is first looped aroundthe draw-head C, as previously described, and then the chain is passedthrough the enlarged portion E' of the link E, and the free end of thechain is then looped around the draw-head O and again passed through theenlarged portion E, but in an opposite direction, the one link, A', atthe closing-point of the loop being engaged with the hook E2, and theother link, A2, at the closing-point of the loop being slipped into theother hook or member E2, the same as above described in reference to thelink D.

The separate link F (shown in Fig. 5) is an open link similar to thelink D, the difference being that in this link one side, F', stands at aright angle to the other side, F2, and the chain A can be readilyslipped through the for other purposes.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An emergencycoupling comprising a chain having aring at one end for the passage of the chain, to form a loop around onemember of the coupling and to allow of forming the free end of the chaininto a second loop passed around the other coupling member, and aseparate link forming two hooks for engagement with two links of thesecond chain-loop,

to close the latter.

2. An emergency-coupling comprising a chain having a ring at one end forthe passage'of the chain, to form a loop around one l member of thecoupling and to allow of forming the free end of the chain into a secondloop passed around the other coupling member, and a separatelink'forming two hooks for engagement with two links of the secondchain-loop, to close the latter, the said separate link being open atthe middle ot' one v member.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE J. HUBBARD.
